No, it is most certainly sorted. It is not sorted during SHOW STATUS, but the array that SHOW STATUS iterates is maintained to be always sorted. > this corroborates with > > https://internal.askmonty.org/buildbot/builders/debian5-i386-fulltest/builds/2153, > > 'nm' pass shows: > main.myisam_mrr w1 [ pass ] 606 > > while 'emb' pass shows: > > +++ > /var/lib/buildbot/maria-slave/debian5-i386-fulltest/build/mysql-test/r/myisam_mrr.reject > 2012-01-26 07:08:17.000000000 -0500 > @@ -563,9 +563,9 @@ > flush status; > show status like 'Handler_mrr%'; > Variable_name Value > -Handler_mrr_extra_key_sorts 0 > -Handler_mrr_extra_rowid_sorts 0 > Handler_mrr_init 0 > +Handler_mrr_extra_rowid_sorts 0 > +Handler_mrr_extra_key_sorts 0 > create table t0 (a int); > insert into t0 values (0),(1),(2),(3),(4),(5),(6),(7),(8),(9); > > if it gives them sorted, how the above is possible? Okay. You have them in the wrong positions (unsorted) in the mysqld.cc. The array is sorted in the init_status_vars(), so I guess this function isn't called in embedded, for some reason. The trivial fix for you would be to put your new Handler_mrr_* variables in the alphabetical order (in mysqld.cc) Regards, Sergei _______________________________________________ Mailing list: https://launchpad.net/~maria-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~maria-developers More help : https://help.launchpad.net/ListHelp
